The SIMD improvements are real nice. Not being conversant with image algorithms, are there any advantages to be found beyond SSE2, or is the tradeoff of disallowing older hardware too much?
I would expect the superwide AVX instructions to be really useful, even if they don't include any more useful instructions.

as far as i know, AVX2 should have suitable integer instructions (and bitwise things for whatever is done to pictures)
AVX is mostly floating point things

pixman works on non-sse cpu's meaning theres a mechanism or another for compatibility
